LED lighting and traditional lighting the biggest difference, LED lighting is a complete electronic products, and traditional lighting is only an electrical products. Therefore, LED lamps and lanterns can be easily associated with various types of sensors, Sensor Bags Light so as to achieve a wide range of control functions such as optically controlled and infra-red.
As a device for signal acquisition and electromechanical conversion, the sensor has already matured its electromechanical technology, and the rise of MEMS technology in recent years has made great strides in the miniaturization, intellectualization,Sensor Bags Light versatility and low cost of the sensor technology. photosensitive sensors, infrared sensors and other types of sensors can be with the LED lighting to form an intelligent control system, the sensor will collect a variety of physical signals converted into electrical signals, through the integrated circuit ad converter, MCU, da Converter to the acquisition of intelligent processing of the signal, To control the LED lighting to turn on and off. Human can be used in the MCU to set a variety of control requirements, Sensor Bags Light the control of LED lights switch time, brightness, color, colorful changes, so as to achieve energy saving goals. The system diagram of the sensor and the LED lamp. Current integrated circuit manufacturing technology has been able to integrate AD, DA, MCU in a 5x5mm or smaller package, installed in the lamp is not occupied area and very convenient.
Landscape Electric LED Street lamp is a highly intelligent and unattended road lighting, the use of wind, sunlight power, battery storage, so the automatic management of energy is very important. Sensor Bags Light The photosensitive sensor is an ideal electronic sensor which can control the automatic switch of the circuit because of the change of illumination of daylight and dark (sunrise and sunset). Sensor Bags Light The appearance of a photosensitive sensor. The resistance plate of the photosensitive sensor is sensitive to the brightness and lightness of the light.
Photosensitive sensor, according to the weather, Sensor Bags Light time period and the area of automatic control store LED lighting opening and closing. Reducing power consumption by reducing its output during the bright daytime can reduce electricity consumption by a maximum of 53% per 200m2 convenience store compared to the use of fluorescent lights. Life expectancy is also about 5-100,000 hours.Sensor Bags Light Under normal circumstances, LED lighting lamp life of about 40,000 hours; the color of the light can also be used RGB colorful changes in the way, Sensor Bags Light so that the mall lights more color, the atmosphere more active; compared with the original blue led with the use of $ fluorescence, the color of purple led with red, green and blue fluorescent bodies is higher.
Infrared sensors work by detecting the infrared rays emitted by the human body. The main principle is: The human body launches about 10um infrared Ray through the Fresnel filter lens enhancement to the pyroelectric element PIR, when the human activity's infrared radiation's launch position will change, Sensor Bags Light the element will lose the charge balance, the pyroelectric effect to release the electric charge, The infrared sensor (PIR) Converts the infrared radiation energy of the Fresnel filter lens into electrical signals, i.e. thermoelectric conversion. In the passive infrared detector in the detection area without human movement, Sensor Bags Light the infrared sensor is sensing only the background temperature, when the human body into the detection zone, through the Fresnel lens, pyroelectric infrared sensors to detect the body temperature and background temperature difference, Sensor Bags Light The signal is collected and compared with the existing detection data in the system to determine whether someone is really waiting for the infrared source into the detection area.
